BIS Certification for Non-Ferrous Sliding Door Bolts (Aldrops)

Brass and other non-ferrous aldrops sit in a slightly different market position from their mild steel counterparts - they are often chosen as much for appearance as for raw function, used where the fitting is visible and expected to match other brass hardware on a door, cabinet or gate. But the security job is identical: a sliding bolt with a loop for a padlock. That dual expectation - look good, hold up under repeated padlocking and weather exposure - is exactly what the certification testing for this product is built around.

Because brass and similar alloys behave differently from steel in terms of strength, workability and corrosion resistance, this material variant has its own Indian Standard distinct from the mild steel and stainless steel aldrop standards.

Certification checks the dimensional accuracy and finish of the bolt body, the strength of the padlock loop and staple, the smoothness of the sliding mechanism, and crucially, the chemical composition of the alloy used, to confirm it genuinely meets the non-ferrous material specification rather than being a cheaper substitute with a brass-toned finish.

Manufacturers producing non-ferrous aldrops for sale in India need this BIS licence in their own name. The order's usual exemptions apply - export-only production, aldrops imported as part of a finished assembly, and small Udyam-registered micro units below specified limits - covered in detail on our main fasteners page.

The path you take depends entirely on where your factory is. If you manufacture in India, the process runs through BIS's standard product certification route - sample testing, factory documentation and a factory inspection before the licence is issued. We have laid out every step on our BIS Certification for Indian Manufacturers page.

If your factory sits outside India, you will go through the Foreign Manufacturers Certification Scheme, which adds an Authorized Indian Representative and typically an overseas factory audit. The full breakdown is on our FMCS guide for foreign manufacturers.

Fasteners are a deceptively tricky category - 19 products, overlapping standards, easy-to-miss exemptions and a demanding factory audit. We work across the entire fasteners QCO, not as a general firm dabbling, but as a team that knows this product family inside out and prepares every document to exact BIS specification so your file keeps moving - for manufacturers in India and around the world.
